roALL WHOM IT MAY CONCERN: p 7

Be it known that I,- STEPHEN B. GREAGEN, of Norwich, in the county of New London, and State of Connec ticut, have invented a certain new and useful Improvement on Machines for Pressing and Moulding.Peat, of which the followingds afull, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, and in which--- Figures 1 and 2 represent sectional elevations, at right an gles to each other, of a pea t-pressing and moulding machine constructed according to my improvement. I v

Like letters of reference indicate like parts in both figures.

The nature of my invention consists in a novel combination, for pressing and'moulding peat, of arevolving cylinder or ring provided with radial. sides to the moulds and arranged within an outer stationary cylinder or partial cylinder, the inner periphery of which, excepting at the edges of the rotating cylinder, where the shape is or may beconcentric, is eccentric to said latter cylinder, in which eccentric portion the radial slides operate and are separately worked in and out by their gear with a fixed cam of-irregular form, receiving in between them from a hopper the ground or prepared peatiand by the eccentric position of the cylinders and sliding sides to the moulds, gradually pressing and forming the peat into suitably shaped'blocks, without the aid of plunger-s, and delivering the blocks through a break or opening in the outer cylinder, where, or a little beyond, a knife or scraper is arranged for clearing the revolving cylinder of any adhering peat.

Referring to the accompanying drawing, A represents a hopper,'iiito which the ground or worked peat is placed, and which communicates with a stationary cylinder or partial outer cylinder, B. Eccentric to this outer cylinder is a revolving shaft, G, that carries and serves to rotate an inner cylinder, D, concentric to the shaft. This inner cylinder is provided with a series of radial slides, b, projecting through it, their inner ends being grooved so as to gear-with a fixed internally arranged and irregular shaped cam, E, and their outer ends, which 'form sides to themoulds, projecting into the space lying-between the outer-and inner cylinders B D. The edges c of the revolving cylinder D, work within ring projections, d, concentric to. the latter. The two cylinders thus arranged, the peat is received from the hopperinto or between the radial slides of the revolving cylinder pro jectiug therein, and by the rotation of said cylinder is carried round the one side of the partial eccentric cylinder, gradually pressing and forming the peat into blocks, azid lclivering the latter through a break or opening, a, on to an endless apron or other conveyer or receiver, the sides of the moulds or rndial slides 6, being each and separately worked inwards diiring the pressing and moulding action, by't-heir gear with the irregular cam E, till after delivery of the blocks they are drawn within the outer periphery of the rotating cylinder, when they will ofl'er no obstruction to a fixed knife or scraper, f, that serves to detach anyv adhering peat from said cylinder. By this arrangement, construction, and operation of partsIit will he observed, the pressing and moulding of the peat is effected gradually by the eccentric position of the two cylinders relatively to each other, without the aid ofplungers, while the radial slides b, working separately inwards during such action, serve to level or smoothen the sides or ends of the blocks, *and draw on them in a manner that prevents theinadhesion to the outer cylinder, which facilitates and makes regular the delivery.

What I claim as my invention, and desire td secure by Letters Patent, is-

1. The combination, with the eccentric outer cylinder B, and irregular" cam E, of the revolving inner cylinder D, with its separately operating radial slides b, forming .sides to the moulds, the whole being constructed and arranged for operation together, substantially as and for the purpose herein set forth.

2. The combination, with the revolving cylinder D, slides 11, and cam E, of the knife or scraperfiarranged for operation in relation thereto as shown and described.
